I launched the Boot Camp Assistant 2.0 on my iMac OS X v10.5. I was hoping to install Windows XP Professional with Built-in Service Pack 3. However, when I tried to partition the disk (32 GB on Windows), a message came up, saying "The disk cannot be partitioned because some files cannot be moved." It states some directions underneath, but, as I am new to Boot Camp and Mac, I don't know what to do and how to do. Please help!
